PDF size under 1 MB becomes inevitable in various scenarios, such as uploading attachments and archiving. Let’s learn how to achieve such a compact size.

The use of PDF format for information sharing and documentation has increased. However, their hefty size creates trouble, especially while sharing or storing. To eliminate this trouble, you must reduce the size of your file to an acceptable level, for example, under 1 MB. To carry out this task, you will find a plethora of online and offline tools.
However, the problem with most of the tools is that they have limited compression capabilities or are unreliable regarding data privacy. To eradicate these loopholes, using a proficient PDF management tool like HiPDF is paramount. In this guide, you will learn how to compress PDF under 1mb online using HiPDF. Also, we will equip you with some offline methods to cover an all-encompassing landscape of PDF compression.
Reasons to Compress PDFs to Less Than 1 MB
Not only easy management, but less PDF size also eases several tasks. Sometimes, it becomes a necessity to compress your PDFs under 1MB. For example, below are some of the compelling reasons for compression:
Restricted File Size Limit
Many online platforms, such as job application sites, educational portals, and government websites, impose strict file size limits. For instance, websites like LinkedIn and Blackboard often restrict file sizes to maintain server performance and avoid excessive storage use.
Email Attachments
Email services often have attachment size restrictions. For example, Gmail allows a size limit of up to 25 MB for sending files via email. Thus, a smaller PDF ensures smooth delivery and downloading by the other end user.
Efficient Storage Management
If you have subscribed to a proprietary cloud storage provider, you cannot take the risk of getting your space occupied by unnecessary, heavy files. On the other hand, you can efficiently manage space by compressing your PDF files with minimal damage done to your file content.
